Guy confident of Libs victory in Victoria

Two polls suggest the Liberals won't win the Victorian election on Saturday but Opposition Leader Matthew Guy insists he's in with a "good chance".

"Our internal polling of the seat-by-seat basis is good, we're positive, we have to be as frank with ourselves as we can and we look at our research and it says we've got a good chance," Mr Guy told reporters while visiting the marginal seat of Cranbourne on Friday.

He dismissed as "inaccurate", polls published by The Age and Herald Sun, which both pointed to the government being returned with a strengthened majority.
